The gap between booked and used is the whole point. Rooms are the most over-booked resource in most offices: recurring meetings that nobody cancels, ninety-minute holds for twenty-minute conversations, and the large boardroom taken by two people because it was the only thing free. Booking data alone will tell you every room is full. Check-in or occupancy data tells you what really happened.
The two figures worth separating are frequency (how often a room is used at all) and capacity fit (how full it is when used). A room booked constantly by two people is a sign you need more small rooms, not more rooms. See space utilisation for the same measure applied to desks.
HybridHero reports room usage against availability, including no-shows released by check-in rules, and rooms can be released automatically when nobody arrives. See meeting room booking.
Common questions
How do you reduce room no-shows?+
Require a check-in and release the room automatically when nobody claims it. That single rule recovers more capacity in most offices than adding rooms, because it returns the recurring bookings nobody cancels.
Why do rooms look busier than they are?+
Because recurring bookings, over-long holds and no-shows all count as booked. Only check-in or occupancy data separates booked from used.
What is a good meeting room utilisation rate?+
It depends on room mix and opening hours, so a single benchmark is misleading. The more useful signal is the gap between your booked and used figures, and whether the sizes people book match the group sizes that turn up.
